...tell me that you may have not have been making it obvious that you liked her by means of subtle flirting. Women are emotional creatures, and if a male proposes himself simply as a friend without signs of interest a woman will commonly accept that.
This is really important, as each person responds differently to various actions. This is where getting to know someone goes into a different level, beyond simply her favorite color or food. You will need to experiment to a degree and study her reaction to your comments and actions. Keep it very simple at first, and build upon that based on her reaction. Once you've managed to learn at least some degree of her personality, then you can start inserting ideas that keeps her mind at work. Keeping her mind wondering is key, as the more she thinks about what you previously, the more likely she is to assess her feelings towards you.Originally Posted by CantGetAWii
Women are emotional creatures, and almost all women seem to love some sense of mystery or generally anything that outlines there emotional preferences.
A good example would be what Warrior said, "well mayeb you should start thinking about me in that way". Some women would see this as a sign of masculinity, and if that is a desired preference in a mate then it could of had a positive reaction. Others, like Frogger, took it as more shovenistic and referenced it as more of an attack - her reaction was more negative obviously.
By studying her reactions to less obvious comments and flirtation will be the key, then you can evaluate your own personality and build from that point on. Once you get a better understanding of her personality and while she does the same with yours (by keeping her thinking), and if all goes well in time even more direct responses will result more positively.
Still need more information, greater detail, however consider improving your subtle flirting and notions of your feelings at this time verses bluntly spilling it out pre-maturely.
